120 PM CDT WED MAY 25 2011

.UPDATE...

UPDATED FOR 18Z AVIATION.

&&

.DISCUSSION...

/ISSUED 1200 PM CDT WED MAY 25 2011/

..SIGNIFICANT SEVERE WEATHER OUTBREAK EXPECTED TO BEGIN UNFOLDING
ACROSS THE MID SOUTH THIS AFTERNOON AND CONTINUING INTO TONIGHT...

DISCUSSION...15Z SURFACE ANALYSIS PLACES AN AREA OF LOW PRESSURE
ACROSS EAST KANSAS WITH A COLD FRONT/DRYLINE EXTENDING FROM THE
LOW ACROSS CENTRAL OKLAHOMA BACK INTO SOUTHWEST TEXAS. ACROSS THE
MID SOUTH TEMPERATURES AT MANY LOCATIONS ACROSS THE MID SOUTH ARE
ALREADY IN THE 70S TO AROUND 80 DEGREES. THIS MORNING DISCUSSION
UPDATE WILL FOCUS ON SEVERE THUNDERSTORM POTENTIAL FOR THE REST OF
TODAY INTO TONIGHT.

12Z LZK UPPER AIR SOUNDING ALREADY INDICATING VERY FAVORABLE
THERMODYNAMICS ALREADY IN PLACE ACROSS WESTERN SECTIONS OF THE
LOWER MISSISSIPPI VALLEY WITH SURFACE BASED CAPE VALUES AROUND
3000 J/KG...PRECIPITABLE WATER VALUES AROUND 1.5 INCHES...0-3 KM
STORM RELATIVE HELICITIES APPROACHING 500 M2/S2. FURTHER SOUTH
ACROSS CENTRAL MISSISSIPPI AN 800-700 MB CAPPING INVERSION IS
PRESENT AND ALSO A VERY UNSTABLE ATMOSPHERE NEAR NASHVILLE.

LATEST 12Z WRF/GFS SHORT TERM MODEL TRENDS ALONG WITH MODIFIED
MORNING SOUNDINGS BASED ON A 89/68 SURFACE BASED PARCEL SUGGEST
SHOWERS AND THUNDERSTORMS WILL BEGIN TO DEVELOP IN THE NEXT 3-4
HOURS ACROSS THE MID SOUTH AS CONVECTIVE TEMPERATURES ARE REACHED
AND A 65 KT MID LEVEL JET STREAK ROTATES ACROSS THE MIDDLE/LOWER
MISSISSIPPI VALLEYS FROM MID AFTERNOON INTO TONIGHT. VERY
FAVORABLE UPPER LEVEL DIVERGENCE PRODUCED BY THE LEFT EXIT REGION
OF A 95 KT UPPER LEVEL JET STREAK...SURFACE BASED CAPE VALUES
APPROACHING 4000 J/KG...LIS BETWEEN -9 TO -10...STEEP 700-500 MB
LAYER MID LEVEL LAPSE RATES AT OR ABOVE 7 C/KM...0-1KM STORM
RELATIVE HELICITIES APPROACHING 400 M2/S2...VERY GOOD DIRECTIONAL
SHEAR...AND FAVORABLE 60DM HEIGHT FALLS SUGGEST POTENTIAL FOR
THUNDERSTORMS TO QUICKLY BECOME SEVERE WITH VERY VOLATILE
THERMODYNAMICS ALREADY IN PLACE ACROSS THE MID SOUTH.

BASED ON THE LATEST TRENDS EXPECTING CONVECTIVE INITIATION TO
BEGIN AS DISCRETE SUPERCELLS WITH OVERALL CONVECTIVE ACTIVITY
GRADUALLY TRANSITIONING OVER TO A QUASI-LINEAR CONVECTIVE SYSTEM
/QLCS/ AS THERMODYNAMICS BEGIN TO DECREASE WITH THE LOSS OF
DAYTIME HEATING LATER TONIGHT. TORNADOES...SOME OF WHICH MAY BE
STRONG/LONG TRACK TORNADOES ARE POSSIBLE ALONG WITH VERY LARGE
HAIL AND DAMAGING STRAIGHT LINE WINDS. A POTENTIAL WILL ALSO EXIST
FOR LOCALIZED FLASH FLOODING FROM HEAVY RAINFALL AS PRECIPITABLE
WATER VALUES WILL AVERAGE AROUND 1.5 INCHES.

OVERALL FORECAST IN GREAT SHAPE FOR THIS AFTERNOON AND TONIGHT.
THE ONGOING WIND ADVISORY MAY NEED TO BE EXTENDED FURTHER INTO
THIS EVENING BUT IS HANDLING THE SITUATION WELL.

WILL UPDATE GRIDS TO MAKE ADJUSTMENTS TO THE AFTERNOON/TONIGHT
FORECAST BASED ON LATEST SHORT TERM TRENDS AND TO RAISE POPS FOR
THIS AFTERNOON MAINLY ALONG AND WEST OF THE MISSISSIPPI RIVER DELTA.
OTHERWISE...FORECAST IS IN EXCELLENT SHAPE.

UPDATED GRIDS WILL BE PUBLISHED SHORTLY.

.PREV DISCUSSION... /ISSUED 323 AM CDT WED MAY 25 2011/

DISCUSSION...

SIGNIFICANT SEVERE WEATHER OUTBREAK EXPECTED LATER THIS
AFTERNOON INTO THIS EVENING...

CURRENTLY...REMNANTS OF SHOWERS AND THUNDERSTORMS FROM LAST
NIGHTS OUTBREAK THAT OCCURRED OVER OKLAHOMA AND WESTERN ARKANSAS
HAVE DISSIPATED. EXPECT CONDITIONS TO REMAIN MAINLY DRY THIS
MORNING ACROSS THE CWA. HOWEVER...THE 00Z NAM INDICATES ADDITIONAL
SCATTERED SHOWERS AND THUNDERSTORMS COULD DEVELOP THIS MORNING INTO
THE EARLY AFTERNOON HOURS OUT AHEAD OF A PRE-FRONTAL TROF. WILL KEEP
30 POPS AS A RESULT.

BY THIS AFTERNOON...A WARM AND JUICY AIRMASS WILL BE IN PLACE ACROSS
THE CWA AS A COLD FRONT EXTENDING FROM A STRONG LOW PRESSURE SYSTEM
LOCATED ACROSS CENTRAL MISSOURI WILL PUSH INTO CENTRAL ARKANSAS.
DEWPOINTS WILL BE IN THE LOWER 70S ACROSS EASTERN ARKANSAS
RESULTING IN CAPE VALUES WILL BE AROUND 4000 J/KG AND LI/S AROUND
-8C. NAM HAS BUMPED UP HELICITY VALUES TO AROUND 400 M2/S2
BY 00Z COMPARED TO LAST NIGHTS RUN. THE GFS KEEPS VALUES BETWEEN
250-350 M2/S2 FROM 18Z THROUGH 6Z. REGARDLESS...STRONG TORNADOES
WILL BE POSSIBLE ALONG WITH DAMAGING WINDS...LARGE HAIL...AND
LOCALIZED FLASH FLOODING. EXPECT THE POTENTIALLY DANGEROUS
SITUATION TO BEGIN AROUND 21-22Z AS SUPERCELLS ARE EXPECTED TO
BEGIN DEVELOPING OVER EAST ARKANSAS/THE MISSOURI BOOTHEEL. SUPERCELLS
WILL ALSO BE MOVING INTO THE AREA FROM CENTRAL ARKANSAS. BY
00Z...WIDESPREAD SEVERE STORMS EXPECTED OVER MUCH OF THE WESTERN
HALF OF THE CWA. THE MEMPHIS METRO AREA WILL LIKELY BE UNDER THE
GUN FOR SEVERE STORMS BETWEEN 23Z-04Z. EVENTUALLY THUNDERSTORMS
WILL MERGE INTO A SQUALL LINE. SQUALL LINE EXPECTED TO PUSH EAST
OF THE MISSISSIPPI RIVER BY 4Z AND WILL BEGIN TO OUT RUN THE FRONT
AND MAY POSSIBLY PUSH SOUTH AND EAST OF THE CWA BY 9Z. A GRADUAL
WEAKENING TREND IS EXPECTED WITH THE LINE. HOWEVER CAN/T RULE OUT
THE SEVERE WEATHER OCCURRING INTO THE OVERNIGHT HOURS. A MODERATE
RISK OF SEVERE STORMS HAVE BEEN ISSUED FOR MUCH OF THE
CWA...BASICALLY NORTH AND WEST OF A LINE FROM CLARKSDALE
MISSISSIPPI TO DECATURVILLE TENNESSEE. A SLIGHT RISK COVERS THE
REST OF THE CWA. STRONG GRADIENT WINDS WILL ALSO OCCUR TODAY OVER
THE WESTERN HALF OF THE CWA AHEAD OF THE COLD FRONT. WILL ISSUE A
WIND ADVISORY.

THURSDAY...FRONT WILL CONTINUE TO PUSH EAST THROUGH THE CWA. DON/T
EXPECT MUCH PRECIPITATION WITH THE FRONT UNTIL EARLY AFTERNOON HOURS
WHEN DAYTIME HEATING MAY ALLOW SOME THUNDERSTORMS TO DEVELOP ALONG
THE FRONT ACROSS NORTHEAST MISSISSIPPI. A FEW OF THESE STORMS COULD
BE SEVERE WITH LARGE HAIL AND DAMAGING WINDS. FRONT SHOULD BE EAST
OF THE CWA BY THURSDAY EVENING. COOLER TEMPERATURES EXPECTED OVER
MUCH OF THE CWA WITH READINGS IN THE 70S.

THURSDAY NIGHT INTO FRIDAY...BRIEF HIGH PRESSURE WILL BUILD INTO THE
CWA. LOWS WILL BE IN THE 50S WITH HIGHS IN THE 70S/80S.

FRIDAY NIGHT INTO SATURDAY MORNING...ANOTHER FRONT WILL SLIDE INTO
NORTHERN PORTIONS OF THE CWA. SHOWERS AND THUNDERSTORMS WILL DEVELOP
ALONG THE FRONT. FRONT WILL BEGIN PUSH BACK TO THE NORTH BY
SATURDAY MORNING AS AN UPPER RIDGE BUILDS INTO THE AREA.

SATURDAY AFTERNOON THROUGH THE REST OF THE FORECAST...UPPER RIDGE
WILL INTENSIFY OVER THE AREA AND WILL BRING HOT CONDITIONS TO THE
MIDSOUTH. HIGHS WILL BE IN THE LOWER TO MID 90S WITH LOWS IN THE
UPPER 60S TO THE MID 70S. CAN/T RULE OUT AN ISOLATED THUNDERSTORM
FROM DAYTIME HEATING BUT FOR THE MOST PART CONDITIONS WILL BE DRY.
WILL CONTINUE WITH A DRY FORECAST.

.AVIATION...

18Z TAF CYCLE

STRONG GRADIENT WINDS WILL CONTINUE THROUGH THE AFTERNOON. EXPECTING
THUNDERSTORMS TO DEVELOP OVER CENTRAL AND EASTERN ARKANSAS BY 22Z
AND BEGIN MOVING ACROSS THE MIDSOUTH. KJBR WILL BE THE FIRST TO BE
HIT BY STORMS...AND KTUP THE LAST. EXPECTING POSSIBLY 2 ROUNDS OF
THUNDERSTORMS. FIRST ROUND WILL BE A BROKEN LINE...WITH THE SECOND
ROUND A SOLID LINE OF THUNDERSTORMS. DUE TO THE POSSIBILITY OF TWO
ROUNDS OF STORMS...HAVE LEFT A 4 HOUR TEMPO GROUP AT ALL SITES
EXCEPT KTUP DUE TO SOME UNCERTAINTY OF THE TIMING OF THE STORMS.
LOW CEILINGS AND VISIBILITIES CAN BE EXPECTED WITH THUNDERSTORMS.
STORMS ARE EXPECTED TO MOVE OUT BY LATE TONIGHT/EARLY TOMORROW
MORNING. WINDS WILL WEAKEN AND VEER TO THE SOUTHWEST AFTER STORMS
MOVE THROUGH. EXPECT SOME CLEARING ONCE THE STORMS MOVE
OUT...HOWEVER A LOW CLOUD DECK WILL SWING AROUND ON THE BACK SIDE
OF THE LOW PRESSURE SYSTEM AND BRING MVFR CONDITIONS TO ALL SITES
BY THURSDAY MORNING. WINDS WILL BECOME MORE WESTERLY AS THE COLD
FRONT PASSES THROUGH EARLY THURSDAY MORNING.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST ARKANSAS...
THE MISSOURI BOOTHEEL...NORTH MISSISSIPPI...AND WEST TENNESSEE.

.DAY ONE...THIS AFTERNOON AND TONIGHT

A SIGNIFICANT SEVERE WEATHER OUTBREAK IS EXPECTED ACROSS MUCH OF THE
MID SOUTH THIS AFTERNOON INTO TONIGHT. THERE IS A HIGH RISK FOR
SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT ACROSS EAST AND
NORTHEAST ARKANSAS...THE MISSOURI BOOTHEEL...AND MOST OF WEST
TENNESSEE...ESPECIALLY ALONG AND WEST OF A LINE FROM SOMERVILLE TO
DECATURVILLE TENNESSEE. A MODERATE RISK FOR SEVERE THUNDERSTORMS
EXISTS ACROSS THE REMAINDER OF THE MID SOUTH.

SEVERE THUNDERSTORMS ARE EXPECTED TO QUICKLY DEVELOP ACROSS THE
LOWER MISSISSIPPI VALLEY AND QUICKLY MOVE EAST TO NORTHEAST ACROSS
THE MID SOUTH. LARGE HAIL...DAMAGING STRAIGHT LINE WINDS...AND
TORNADOES ARE POSSIBLE WITH ANY THUNDERSTORMS THAT BECOME SEVERE.
SOME OF THESE TORNADOES MAY ALSO HAVE THE POTENTIAL TO BECOME STRONG
AND LONG TRACK TORNADOES. ALONG WITH THE SEVERE THUNDERSTORM
THREAT...LOCALIZED FLASH FLOODING FROM HEAVY RAINFALL IS ALSO
POSSIBLE WITH THE THUNDERSTORMS.

STRONG GRADIENT WINDS WILL ALSO BE POSSIBLE ACROSS THE WESTERN
HALF OF THE MIDSOUTH THROUGH THE EARLY EVENING HOURS. A WIND
ADVISORY REMAINS IN EFFECT UNTIL 7 PM CDT.

MODERATE RIVER FLOODING WILL CONTINUE ALONG THE MISSISSIPPI RIVER
NEAR OSCEOLA...AND ALONG THE ST FRANCIS RIVER SOUTH OF INTERSTATE 40.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THERE WILL BE A CONTINUED THREAT FOR A FEW SEVERE THUNDERSTORMS
WITH DAMAGING WINDS...LARGE HAIL...AND ISOLATED TORNADOES ON
THURSDAY MAINLY ACROSS NORTHEAST MISSISSIPPI.

THE MISSISSIPPI RIVER WILL REMAIN ABOVE FLOOD STAGE THROUGH MOST
OF THIS WEEK...WHICH WILL CONTRIBUTE TO BACKWATER TRIBUTARY FLOODING.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS REQUESTED THIS AFTERNOON AND TONIGHT.
